Switzerland’s financial regulator said an unnamed former bank chief executive must pay 730,000 Swiss francs ($774,150) and banned him from dealing securities for six years over unlawful insider trades made through his wife’s accounts.

The Swiss Financial Market Supervisory Authority, or Finma, said the CEO used information received on the job and shared inside information with others for share trades, breaking internal rules and supervisory law. A spokesman declined to name the CEO or whether any criminal proceedings are under way.
